Lucy in the sky with diamonds. A brilliant Beatles song explaining two of Sir John Lennons LSD trips. You can also use it to refer to the Psychoactive drug LSD (acid)

*picture yourself in a boat on a river, with tangerine trees, and marmalade skies*
Will: What did you do last night?

Sean: Went to see lucy in the sky with diamonds!

Will: The Beatles were performing?

Sean: Nope, I tripped the F**k out!
